The device has a counterweight (20) fitted to a turbomachine rotor and including two radial bearing surfaces (23, 24) oriented in two opposite radial directions. The surfaces cooperate with two radial bearing surfaces arranged on the rotor, and a bolt with a nut holds the counterweight against a coupling flange (10) fixedly attached to the rotor. The flange has an axial cylindrical portion and a radial portion in which notches are arranged for the passage of the bolt to fix the counterweight. |
